ABSTRACT:
A roll film winding mechanism is provided for film of the type which is wound on a flanged winding spool with superposed liner paper for protection against light intrusion and accidental exposure. The winding mechanism includes a tension roller disposed between a support member for guiding the film and the spool. The tension roller is arranged to bias the film together with the liner paper to provide a controlled winding tension, and to inwardly curl the longitudinal edges of the film and liner paper toward the spool shaft as they are wound to assure a secure light seal.
